Subject: [Mspgcc-users] Setting code location
Reply-To: [email protected]
mspgcc provides a variable - _etext - to mark the end of .text section. Is
=
there any way to set the beginning of this section? I am porting code =
written with IAR to mspgcc. The code has following statement in the =
LNK430.xcl file:
-Z(CODE)CODE,CDATA0,CONST,CSTR,CCSTR#2A00-FFDF
which gives a different code location.

Hi Amol,
for porting IAR code to mspgcc i use the following snips
In my own linker file:
-------8<---------
MEMORY
{
[..]
IAR_GDATA(rw) : ORIGIN = 0x1200, LENGTH = 0x0400
text (rx) : ORIGIN = 0x1600, LENGTH = 0xCA00
[..]
}
-------8<---------
and further down in the SECTIONS area:
-------8<---------
.IAR_GDATA :
{
*(.IAR_GDATA)
. = ALIGN(2);
*(.IAR_GDATA.*)
} > IAR_GDATA
-------8<---------
in my code this looks like:
-------8<---------
#ifndef __GNUC__
#pragma memory = constseg ( GDATA )
#endif
#ifdef __GNUC__
__attribute__((section(".IAR_GDATA")))
#endif
const gDefaults gDefCh1 = {
[...]
-------8<---------
The line in the MEMORY area
text (rx) : ORIGIN = 0x2A00, LENGTH = 0xD5E0
would match to your
-Z(CODE)CODE,CDATA0,CONST,CSTR,CCSTR#2A00-FFDF
Ciao,
Helmut
